    Looking at using that this spring thru our first apps - instead of running trimic and deminsion. Any good? Who has used it?

    Victor suggested we try it. So we started using it last summer. It worked GREAT! Knocks out crabgrass & foxtail FAST. Even "killed" (not suppress) nutsedge.

    It's expensive, so I would only use it in a backpack sprayer (hope you have a battery-powered one). Victor has more experience with it than I do. Hope he chimes in.

    Where are you located? I'm originally from Primghar.:waving:

    I'm hoping I can help you with this, Q4 is a post emergant crabgrass,broadleaf and nutsedge control which means you will need to use dimension or another pre E like you always would and than monitor with Q4 later in the season after some germination has occurred. if yopu were to go ouit the door with Q4 instead of a Pre m you the Q4 would be gone in a very short time, almost no residule.
    The short of this is you don't wanna use a post as a pre in most cases, and since some people are getting Q4 for like 100.00 / acre heck I might use it for everything.

    While I agree that Q4's a wonderful product, you definitely will want to still apply a good pre em (like Dimension). I normally don't whip out the Q4 backpack though until late May, or June. It's too expensive to use before that. Until that time of year, I use a good broadleaf herbicide like Speedzone exclusively.

    By the time June rolls around, you're going to want to have Q4, or at least some other product like Surge that will be able to knock out any nutsedge you come across. I keep Q4 loaded this time of year, because unlike Surge, it not only knocks out nutsedge, but it also knocks out crabs and foxtails like Larry said.

    In case you didn't know it Meets, June is prime time to really knock out nutsedge. That's when it's most vulnerable in our zone. Remember that.

    I will agree with victor. I used Q4 for the first time last year and it is a really good product. It is a little spendy but not one client complained when they where billed for it. I had alot of break through with crabgrass in some yards last year and almost every client thanked me for getting rid of the crabgrass, again no complaints on the price I charged them. It worked so well in one neighborhood that I picked up new clients since there national lawn spraying service couldnt get rid of there breakthrough crabgrass.

    Q4 - wondering how well it worked. I was told by my rep to try during the 2nd app that is applied. By that time it will show what I missed or crept thru. Being from primghar - I have a about a days worth of spraying there!!

    I used it last year for my mid summer spot treatment. It worked extremely well for that but I think you would go poor using it for a blanket application.

    I have used Q4 for two years awesome product. would not reccomend blanket applying it thought. It does have some phytotoxicity if conditions are not favorable, be careful. Mixed with a little surfactant works even faster

    I think I may pre-order some for the discount and give it a try. So basically from what I am reading here - great product for extra/blacket protection.

    Again my biggest problem area is crab grass. Be it our 1st app, weather timing, etc doesn't always work in your favor.

    I started using Q4 this past year and great results with it, even on ground ivy!!! I did find that if I spiked the tank with Quicksilver, I only had to apply once to ground ivy for a good kill. I will find out this spring how effective it was in totally taking it out, I won't go to the bank just yet. Hopefully the $ will drop on this product, so that it can used more offten, rather than the spot spray for really troubled lawns.
